Nokia today confirmed that that Windows Phone 8.1 update will be coming for all Lumia Windows Phone 8 smartphones as an over-the-air update starting this summer.

Windows Phone 8.1 introduces a wealth of new features, including more at-a-glance content with LiveTiles, faster ways to connect and type with the Word Flow keyboard, one easy swipe to important notifications with Action Center and (starting in the US) a personal and pro-active voice assistant called Cortana.

Along with the OS update, Nokia is also preparing its own update which is named Nokia Cyan. It will combine Windows Phone 8.1 and brand-new Lumia features into one update package. This includes enhancements to the camera roll and Creative Studio, as well as a new and improved Nokia Storyteller app, for sharing stories as a video slideshow on social networks.
